The Zagros Mountains, located in southwestern Iran, is a geological wonder formed by the collision of the Eurasian Plate and the Arabian Plate. It is a geological phenomenon in which the salt layer flows upward under pressure deep underground during geological time, forming a dome shaped structure. The formation of salt domes is closely related to the sedimentary environment and tectonic history of the region, and is an important component of oil production in the Persian Gulf. Salt domes are formed by the upward flow of low-density salt layers under pressure in underground rock formations, which bend and cover the rock layers. As erosion progresses, the surrounding softer rocks are removed, revealing salt domes.

The Persian Garden in Iran, designated as a World Cultural Heritage site in 2011, consists of nine gardens located in nine provinces. These nine gardens were constructed at different times, with the earliest dating back to the 6th century BC. The main design concept of Persian gardens highlights the symbolic imagery of the four elements of Eden and Zoroastrianism - sky, water, earth, and plants. All gardens are divided into four parts, and water plays an important role in irrigation and decoration. Pavilions, pavilions, walls, and precise water flow irrigation systems are important features of gardens.
